Electroplating

Electroplating is the process of using an electrical direct current to coat an electrically conductive object with a thin layer of metal. EPi offers a variety of high-quality electroplating processes that are ideal for all types of metal finishers. Learn More

Cleaners

All metals need to be cleaned prior to electroplating, blackening, or finishing. Metalworking fluids and carbonaceous smut need to be removed in a soak, spray, electroclean, or ultrasonic cleaning. A properly cleaned part will have excellent adhesion and be brighter, blacker, and smut-free. Learn More

Acid Salts

Dry-powdered and liquid acid salts are specifically formulated for removing rust, scale oxides, stains, and smut from a variety of metal surfaces. Acid salts are also used to activate metal surfaces for further finishing. Learn More

Recently, a large US base power management base company conducted a study on EPI's E-Brite 50/50 alkaline non cyanide silver plating process, which has been previously used on bus bar, electronic components, and other electrical switching parts.

The hardness of the E-Brite 50/50 alkaline non cyanide silver was found to be 95-110 KHN 25 which is harder than cyanide silver deposit from a solution with no additives. The hardness is measured on a cross section sample with a Knoop diamond indented at a load of 25 grams.

Why E-Brite 50/50? If it plates harder than cyanide silver process that means you can use 20-40% less silver plate when plating from a E-Brite 50/50 process than a cyanide silver process because it will wear longer than the cyanide silver plate.
